Yes, it all used to work fine and after changing the housing of my K750i, it all went belly-up. This is what happens:
-SE can send/receive via bluetooth to my samsung phone
-SE can receive from my Sony Vaio laptop but cannot "find" it when I want to send data to it. The laptop configuration is all perfect and computer is able to detect phone.
Anyone have an idea what the problem may be? Thanks!
